Patent Images
1. A compressive dressing which may be used to treat a finger, hand, toe, foot, limb, torso or head wound or a surgical site comprising:
- a) a conformable, porous, self-adhering elastomeric substrate wherein the substrate does not adhere to clothing, hair or skin and which has a compressive force when extended that is sufficient to hold the dressing in place for a period of time to provide a therapeutic effect to the wound; and
b) an absorbent layer flexibly bonded to the self-adhering substrate wherein the absorbent layer is offset to one end of the self adhering substrate.

Abstract
The present invention relates to a wound dressing 10 that is a porous, self-adhering elastic 14 bandage which may be compressively wrapped around a wound and which is capable of absorbing fluids and wound exudate. A preferred embodiment of the wound dressing 10 is a self-adhering elastic substrate 14 which does not adhere to clothing, hair or skin having a compressive force when extended that provides a therapeutic benefit and which is flexibly attached or fixed to an absorbent layer 12.

3. A compressive dressing which may be used to treat a finger, hand, toe, foot, limb, torso or head wound or a surgical site comprising:
-
a) a conformable, porous, self-adhering elastomeric substrate selected from the group consisting of partially extended, longitudinally aligned elastic yarns bound with a polymeric binder between two porous nonwoven fibrous webs and a conformable, porous, web of melt blown or spunbond, elastomeric polyurethane microfibers, wherein the substrate does not adhere to clothing, hair or skin and which has a permanent compressive force when extended which is sufficient to hold the dressing in place for a period of time to provide a therapeutic effect to the wound, and b) an absorbent layer covering at least a portion of the self-adhering substrate, wherein only a portion of the absorbent layer is bonded to the self-adhering substrate, whereby the absorbent layer minimally inhibits expansion or contraction of the self-adhering substrate. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)

6. A compressive dressing which may be used to treat a finger, hand, toe, foot, limb, torso or head wound or a surgical site comprising:
-
a) a conformable, porous, self-adhering substrate selected from the group consisting of partially extended, longitudinally aligned elastic yams bound with a polymeric binder between two porous nonwoven fibrous webs and a conformable, porous, web of melt blown or spunbond, elastomeric polyurethane microfibers, wherein the substrate does not adhere to clothing, hair or skin and which has a permanent compressive force when extended which is sufficient to hold the dressing in place for a period of time to provide a therapeutic effect to the wound, and b) an absorbent layer flexibly bonded to and covering at least a portion of the self-adhering substrate, wherein the self-adhering substrate is stretched before the absorbent layer is fixed by adhesive to the self-adhering substrate, wherein the absorbent layer minimally inhibits expansion or contraction of the self-adhering substrate.
